Radiation Increase from Fukushima measured in Northeastern Japanese Forests

nsnbc , – Levels of the radioactive isotope cesium from the crippled Fukushima Daiichi power plant in northern Japanese forests have almost doubled within one year and will continue increasing as the forests accumulate the isotope.

The Japanese Nikkei Daily reported yesterday that measurements, made in forests between 60 and 120 kilometers from the crippled Fukushima Daiichi nuclear power plant show, that cesiumlevels in sampled leaves have almost doubled within one year.

Measurements taken in June 2012 showed that more than half of the sampled leaves contained 26.000 bequerels per kilogram.

Measurements taken one year later, in June 2013, showed that more than half of the leaves contained 42.000 bequerels per kilogram. Soil samples, representing the surface earth up to a depth of ten centimeters, increased from about 721 to 3.000 bequerels.
